Linear Regression Model
Model equation:
Yi = α + β × Xi + εi
Top border of price channel:
Exp(Yi) = Exp(a + b × Xi + 2 × s)
Bottom border of price channel:
Exp(Yi) = Exp(a + b × Xi – 2 × s)
where:
i - observation number
Yi - natural logarithm of SBUX price
Xi - time index, 1 day interval
σ - standard deviation of εi
a - estimator of α
b - estimator of β
s - estimator of σ
Exp() - calculates the exponent of e
Primary Trend
Start date: June 11, 2025
End date: November 5, 2025
a = 6.2830
b = -0.0010
s = 0.0273
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0010) – 1
= -31.35%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0273) – 1
= 11.52%

Top border of price channel:
Exp(Y1,152)
= Exp(a + b × X1,152 + 2 × s)
= Exp(a + b × 1,678 + 2 × s)
= Exp(6.2830 + -0.0010 × 1,678 + 2 × 0.0273)
= Exp(4.6080)
= $100.28
Bottom border of price channel:
Exp(Y1,152)
= Exp(a + b × X1,152 – 2 × s)
= Exp(a + b × 1,678 – 2 × s)
= Exp(6.2830 + -0.0010 × 1,678 – 2 × 0.0273)
= Exp(4.4989)
= $89.92
